Abstract
Various embodiments of reinforced mirror microstructures for a surface micromachined optical system are disclosed. Multi-layered and structurally reinforced mirror microstructures are disclosed, including both two and three-layer microstructures. Adjacent structural layers in these multi-layered mirror microstructures may be structurally reinforced and interconnected by a plurality of vertically disposed columns, or by a plurality of at least generally laterally extending rails or ribs, or some combination thereof. Various embodiments of a single layered mirror microstructure with a structural reinforcement assembly that cantilevers from a lower surface thereof is also disclosed.
